Abstract:

A Planning Model Change Request (PMCR) is created by the Transmission Service Provider (TSP) Planning group when a future change in the operational grid is anticipated, expected or planned. These changes may be created 3 months to 5 years in advance of the actual implementation of the change. When a PMCR is about to be implemented, the TSP will generate an Network Operations Model Change Request (NOMCR) to be input into the operational model. To ensure the change is properly addressed, the ERCOT Model Coordinator will initiate notifications to the planning and operations TSPs to convert the PMCR to an NOMCR.
